Ask 'Steve P', on this board, what a thoughtfully prepared, decade old Mille will do, in the hands of a skilled and talented racer, against a multi-time ASRA national champion on a thermo nuclear superbike kitted KTM RC8. Or, just have a look at the CCS MidWest Expert Supertwins race results.
At all but the top-of-the-food-chain levels of club racing, it's more about the rider than the bike. Yes, the latest and greatest is faster, lighter, more powerful. And probably easier to go fast on. But, it's a matter of degree, and the RSV2s aren't that far behind.
